As expected, unfortunately we have some clearly heavily abused areas in Brazil.
I just found one when reviewing and it's just hard to believe.
It's around Av. Curió - Ponta da Areia, Caravelas - BA, 45900-000, Brazil (-17.733583,-39.185214)
There's even a photosphere to confirm, so it looks ok:
But then when we look at the duplicates:
What? 2 pairs of duplicates? Let's see the rest...
We can create a small game... How many replicated POIs can you find?
